Abstract

L'invention concerne un pneumatique pour véhicule, notamment pour l'utilisation dans des conditions de conduite hivernales, avec une bande de roulement qui est divisée en blocs profilés (2, 5, 6) par des gorges (4), des rainures (3, 14) et similaires. Des blocs profilés (6) sont munis à chaque fois d'au moins trois entailles (12) qui s'étendent sensiblement dans une direction coïncidente, à chaque fois suivant un angle de 45° au maximum, par rapport à la direction transversale de la bande de roulement. La bande de roulement présente des blocs profilés (6) dont les entailles (12) forment avec la direction transversale de la bande de roulement des angles de différente taille (a1 à a6), qui, en commençant au niveau d'une des deux entailles (12) les plus extérieures dans la direction périphérique du bloc profilé (6), sont de plus en plus grandes ou de plus en plus petites par incréments d'une entaille (12) à l'autre.
